And it's happening on 19 and on 18. Too tired tonight to pursue this further...I'll tackle it again tomorrow. Thanks Chris and Matthew ! I checked grub.cfg again and it does contains all the kernels...so then I stripped down /etc/default/grub.cfg to the bare minimum and lo and behold all the kernels display. I don't know which option or if any option was fouling up the display..but I am happy even with the resulting bare bones menu.

Maybe the mkconfig program isn't samrt enought or maybe I should go ahead and write my own. I don't have an install to look at at the moment but I'm not surprised that (assuming that F17's the last distro installed) all your entries are called F17... given that you have the same 4GB /boot for all your distros. I don't have copies of 10_linux, grub2-mkconfig, and grub2-mkconfig_lib (or maybe it's not renamed in Fedora and is grub-mkconfig_lib) but I suspect that it's not only the menuentry titles that are the same in grub.cfg but that the root= values on the linux lines are all the same too and not pointing to the slackware / for the slackware kernels and the ubuntu / for the ubuntu kernels. Maybe you can combine the logic of 10_linux and 30_os=prober for grub2-mkconfig to do what you'd like it to do. -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test

Maybe the mkconfig program isn't samrt enought or maybe I should go ahead and write my own. You share a boot partition between all the distros? Yeah, grub2-mkconfig as it stands really has no way of figuring out which one's which in that case. You don't strictly have to edit/rewrite grub2-mkconfig, as long as Fedora is the only distro messing with GRUB. Fedora does not rerun grub2-mkconfig on update, the grub2.cfg is patched by grubby. If you go in and fix /boot/grub2/grub.cfg, it should stay. (This is *not* the case for most other distros, however.) If you do want to hack on grub2-mkconfig, it runs scripts located in /etc/grub.d/ to make up the configuration. See /etc/grub.d/README for details. Note that changes there could get clobbered on grub2 updates, so be careful. -T.C. -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
